Pls solve this question as quick as possible!!!!! A hydrocarbon on complete combustion produces
176 g of carbon dioxide and 90 g of water. What will
x the formula of hydrocarbon be? Also give balanced

C4H10 or C2H5
- For complete combustion of hydro carbon 90g of water is required so for 90g of water
- number of moles =given weight/gram molecular weight
- so,no. of moles of water=90/18=5 moles
- but water contain 2 moles of hydrogen
- so,for H no of moles=5×2=10 moles
- for co2 no of moles =176/44=4 moles of carbon dioxide
- for each co2 molecule only one carbon is present so, 4 moles of carbon is present
- so, by this10/4=5/2
- There fore C2H5 is the hydro carbon
EQUATION
C4H10+61/2O2 gives rise to 4CO2+5H2O
